Sorry to bring up an older thread - but Shell Rotella Ultra ELC isn't EC-1 rated. Shell Rotella ELC (non "ultra") is. Have any of you run high mileage on a 6.0 PSD like the OP has (I have one too which is why I'm curious) on shell rotella ultra? Any ill-effects?

It is starting to seem to me like CAT EC-1 rating is somewhat broad - CAT ELC above does have 2-EH, Peak final charge is EC-1 rated but DOESN'T use 2-EH, formulations both with and without nitrite are also EC-1 rated. I haven't found anything yet about what defines the EC-1 rating exactly.

I saw this recently: https://www.youtube.com/watch?v=6VLMfUz34R0 Discussion about cleaning starts about 8:00 minues in. They are saying that the oil has to get up to temperature before it starts "trapping contaminates" at 13:00 minutes in - they are talking about flushing engines out by using...

do you have a picture of the back of that jug? what is the API rating?

New user here. I read the motor oil university on this website but I need some help with something and I'd appreciate some insight. Something I've always wondered was why do manufacturers recommend different high temp (say 5w30 or 5w40) weights for their vehicles. If I understand correctly, the...
